Meteor Crater, known to scientists as Barringer Meteorite Crater, is a meteorite impact crater site in northern Arizona, between Flagstaff and Winslow along Route 66 / I-40. I made this video as a research project for my astronomy class. The video script with a bibliography is available in PDF and Word Document formats. I also posted a Barringer Meteorite Crater photo set on Flickr from my visit to the crater. The video is licensed under a Creative Commons Attribution 3.o License.

Recorded 2/17/2013 Things are getting back to normal. Joe's PC is back to full functionality. Tonight we have meteors, genetic patents, a practically unserviceable tablet, and ZOMBIES! Plus, Kevin does a mime show. It's really fantastic. Really it is. You'll have to listen to believe it. Topics: rambling, idiots, meteorite, blackberry, zombies
Boone Titanium Rings is the industry leader in Meteorite Rings, Carbon fiber inlay, and Hardwood inlay rings. We pioneered the use of these materials in titanium rings. We are also leaders in titanium tension sets, making the tough asymmetric designs that others can't do. We have a complete line of Black Zirconium rings, including tension set engagement rings.

In recent years, much effort has been spent examining the residual stress-strain states of advanced composites. Such examinations are motivated by a number of significant concerns that affect composite development, processing, and analysis. The room-temperature residual stress states incurred in many advanced composite systems are often quite large and can introduce damage even prior to the first external mechanical loading of the material. These stresses, which are induced during the cooldown... Topics: TITAN, SATELLITE SURFACES, ALBEDO, DICHOTOMIES, PHOTOMETRY, METEORITE CRATERS, INFRARED IMAGERY
The Anthropometry and Biomechanics Laboratory in the man-Systems division at NASA's Johnson Space Center has as one of its responsibilities the anthropometry and strength measurement data collection of astronaut candidates. The anthropometry data is used to ensure that the astronaut candidates are within the height restrictions for space vehicle and space suit design requirements, for example. The strength data is used to help detect abnormalities or isolate injuries to muscle groups that could...

ANALYSIS OF THERMAL STRESSES IN AN INFINITE, ELASTIC, ORTHOTROPIC CYLINDER SUBJECTED TO AXISYMMETRIC HEATING IS CONSIDERED. EXACT FORMULAS WERE DERIVED FROM CONSTANT ELASTIC PARAMETERS AND FOR ELASTIC PARAMETERS VARYING ALONG THE RADIUS. A COMPUTATIONAL ALGORITHM IS GIVEN FOR A LAMINATED CYLINDER WITH AN ARBITRARY NUMBER OF LAYERS. A SYSTEM OF FIRST-ORDER DIFFERENTIAL EQUATIONS SUITABLE FOR NUMERICAL INTEGRATION WAS OBTAINED.

Effect of inlet-air pressure and temperature on the performance of the X24-2 10-Stage Axial-Flow Compressor from the X24C-2 turbojet engine was evaluated. Speeds of 80, 89, and 100 percent of equivalent design speed with inlet-air pressures of 6 and 12 inches of mercury absolute and inlet-air temperaures of approximately 538 degrees, 459 degrees,and 419 degrees R ( 79 degrees, 0 degrees, and minus 40 degrees F). Results were compared with prior investigations. Topics: METEORITIC COMPOSITION, OCEAN BOTTOM, EJECTA, METEORITE CRATERS, DEPOSITION, METEORITE COLLISIONS,...
This report summarizes the results of the first 12 months of our program to study the interaction of the Earth's magnetosphere with the solar wind on the far flanks of the bow shock. This study employs data from the ISEE-3 spacecraft during its traversals of the Earth's magnetotail and correlative data from spacecraft monitoring the solar wind upstream. Our main effort to date has involved assembling data sets and developing new plotting programs. Two talks were given at the Spring Meeting of...

To realize quality microgravity science on the International Space Station, many microgravity facilities will utilize the Active Rack Isolation System (ARIS). Simulation capabilities for ARIS will be needed to predict the microgravity environment. This paper discusses the development of a simulation model for use in predicting the performance of the ARIS in attenuating disturbances with frequency content between 0.01 Hz and 10 Hz. The derivation of the model utilizes an energy-based approach.... Topics: METEORITES, ORGUEIL METEORITE, EXOBIOLOGY, EXTRATERRESTRIAL LIFE, IGNEOUS ROCKS, PETROLOGY,...

This document describes a general purpose Requirement Specification Language (RSL). RSL is a hybrid of features found in several popular requirement specification languages. The purpose of RSL is to describe precisely the external structure of a system comprised of hardware, software, and human processing elements. To overcome the deficiencies of informal specification languages, RSL includes facilities for mathematical specification. Two RSL interface tools are described. The Browser view...

University Archivist and Head, Rob Spindler and Curator Karrie Porter Brace discuss Arizona State Universityâs early research scientists durring the first days of transformation from a small college to a true university. Their work at ASU helped others to understand venomous animals, meteorites, genetics, rare earth oxides, frozen deserts, and local geology. The exhibit ASU Science Pioneers 1955-1970 was developed from the University Archives of Arizona State University Libraries. It features...

The simulation employed all six rigid-body degrees of freedom and incorporated aerodynamic characteristics based on wind-tunnel data. The flight instrumentation included a localizer and a flight director which was used to capture and to maintain a two-segment glide slope. A closed-circuit television display of a STOLport provided visual cues during simulations of the approach and landing. The decoupled longitudinal controls used constant prefilter and feedback gains to provide steady-state...

This work presents results from large-eddy / Reynolds-averaged Navier-Stokes (LES/RANS) simulations of the well-known Burrows-Kurkov supersonic reacting wall-jet experiment. Generally good agreement with experimental mole fraction, stagnation temperature, and Pitot pressure profiles is obtained for non-reactive mixing of the hydrogen jet with a non-vitiated air stream. A lifted flame, stabilized between 10 and 22 cm downstream of the hydrogen jet, is formed for hydrogen injected into a vitiated...

Refractory inclusions, considered to be the oldest solids formed in the solar nebula. (4567.2 0.6 Ma) , are common in many carbonaceous and in some ordinary and enstatite chondrites. High-precision Pb- Pb ages for CAI s and chondrules (from different meteorites) suggested that chondrule formation appeared to have started about 2 Ma later than that of CAIs . However, recent 26Al/26Mg data suggest simultaneous formation of CAI s and chondrules in Allende . The I-Xe ages of CAI s in...

Constant stress-rate (dynamic fatigue) testing has been used for several decades to characterize slow crack growth behavior of glass and ceramics at both ambient and elevated temperatures. The advantage of constant stress-rate testing over other methods lies in its simplicity: Strengths are measured in a routine manner at four or more stress rates by applying a constant crosshead speed or constant loading rate. The slow crack growth parameters (n and A) required for design can be estimated from... Topics: ANNEALING, DEPOSITION, COOLING, CRYSTALLIZATION, METAMORPHISM (GEOLOGY), MELTING, IMPACT MELTS,...
The investigation 'Dusty Plasma Dynamics Near Surfaces in Space' is an experimental and theoretical study of the dynamics of dust particles on airless bodies in the solar system in the presence of a photoelectron sheath generated by solar ultraviolet light impinging on the surface. Solar UV illumination of natural and manmade surfaces in space produces photoelectrons which form a plasma sheath near the surface. Dust particles on the surface acquire a charge and may be transported by electric... Topics: PREVENTION, METEOROIDS, ASTEROIDS, COMETS, LASERS, ABLATION, DETECTION, EARLY WARNING SYSTEMS,...
